A swollen foot can be treated as follows: First, an x-ray or CT examination of the injured foot should be performed to rule out any fracture. If there is a fracture, treat it as such; if the fracture is heavily displaced, surgery may be considered. If the fracture is linear or undisplaced, fixation in a cast or brace is sufficient. If there is no fracture in both feet, the following treatment should be carried out: 1. Braking the injured foot for 2 weeks and fixing it with a brace or cast, which is beneficial to the recovery of the injured foot and can play a role in relieving pain. 2. Elevating the injured foot while sleeping is beneficial to blood flow and can reduce local swelling. 3. applying cold compresses at an early stage. You can use frozen mineral water wrapped in a towel to apply cold compresses to the injury, which can play a role in relieving pain, stopping bleeding and reducing swelling. 4, oral medication. You can take oral pain medication and blood circulation drugs to treat, if in the acute stage after 3 days, you can also carry out local microwave physiotherapy or far-infrared physiotherapy to promote the recovery of the injured foot soft tissue.
